An ex-wife of U.S. Rep. Joe Barton was not surprised when explicit photos of the congressman surfaced online last month, the woman told WFAA-TV (Channel 8).

Terri Barton said the Ennis Republican was having affairs when the couple were married, and said it wasn't long after their wedding day that she became suspicious. She said she filed for divorce twice, but backed out.

Joe Barton, 68, announced Thursday that he would not seek re-election following scrutiny after sexual images he shared while in an extramarital relationship were posted on Twitter.

Barton has apologized and said the sexual relationships he had with multiple women while married, but separated from, his second wife, were consensual.

The revelations also led to an apology, which she said she had never received. She told the station she is struggling to forgive, but wants people to know that he needs help.

"The lies he would tell these women to get them to interact with him were wrong. They were false," she told WFAA. "He was telling the exact same lies to my family and people believed him because of his position and power."
